2. Encoder receiver transmitter - Wikipedia

   en.wikipedia.org/wiki/Encoder_receiver_transmitter

   Encoder receiver transmitter (ERT) is a packet radio protocol developed by Itron for automatic meter reading. [1] The technology is used to transmit data from utility meters over a short range so a utility vehicle can collect meter data without a worker physically inspecting each meter. The ERT protocol was first described in U.S. patent ...

3. Gas meter - Wikipedia

   en.wikipedia.org/wiki/Gas_meter

   Gas meter. A gas meter is a specialized flow meter, used to measure the volume of fuel gases such as natural gas and liquefied petroleum gas. Gas meters are used at residential, commercial, and industrial buildings that consume fuel gas supplied by a gas utility. Gases are more difficult to measure than liquids, because measured volumes are ...

4. Automatic meter reading - Wikipedia

   en.wikipedia.org/wiki/Automatic_meter_reading

   Automatic meter reading (AMR) is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. This technology mainly saves utility providers the expense of periodic ...

   Some vessels store liquid until it is pumped out. The controller (LIC) acts to start and stop the pump within a specified band. For example, it may start the pump when the level rises to 0.6 m and stop the pump when the level falls to 0.4 m. High and low level alarms (LAH and LAL) warn operating personnel that levels are outside predefined limits.

   A meter serial number [1] (MSN, or 'meter ID') is an alphanumeric reference used in Great Britain to identify an electricity meter. Although meter serial numbers are intended to be unique, this can not be assured and duplicate serial numbers do exist. There are a variety of formats used over many years, but many meter serial numbers take the ...

7. Gas meter prover - Wikipedia

   en.wikipedia.org/wiki/Gas_meter_prover

   A gas meter prover is a device to verify the accuracy of a gas meter. Provers are typically used in gas meter repair facilities, municipal gas meter shops, and public works shops. Provers work by passing a known volume of air through a meter, while monitoring the gas meter's register, index, or internal displacement.

8. Custody transfer - Wikipedia

   Quality systems (gas chromatographs to measure energy content of natural gas and sampling systems for liquid); Calibration using in-place or mobile provers for liquid, or master-meter for liquid or gas; and; Supporting automation. A typical liquid custody transfer skid includes multiple flowmeters and meter provers. Provers are used to ...

9. Multiphase flow meter - Wikipedia

   en.wikipedia.org/wiki/Multiphase_flow_meter

   A multiphase flow meter is a device used to measure the individual phase flow rates of constituent phases in a given flow (for example in oil and gas industry) where oil, water and gas mixtures are initially co-mingled together during the oil production processes.
